Could timing cause overheating and white smoke in tailpipe


the question is --is the engine running and performing correctly
if the marks are off by one tooth then it was installed incorrectly but answer the first question--is it running good
if it is then the timing is correct or else the performance will be off
AS to the overheating and white smoke , have a compression test done as it could be a head gasket or cracked head

Backfiring when starting, sputtering, light white smoke out tailpipe, fluid out the tailpipe, check engine light is blinking.


When the check engine light is on, the light is telling the driver the computer has found a problem that may affect performance or emissions. You should get the computer scanned for trouble codes.
The smoke and fluid could be coolant or trans fluid being burned thru the cylinders.

2005 3.5l some times smokes oil then stops


Smoke oil? For what your thinking that is oil? Smoke coming from the tailpipe is not good news, but does not necessarily mean the engine needs rebuilding. First, you need to determine what color of smoke is coming from the tailpipe
* White smoke is caused by water and or antifreeze entering the cylinder, and the engine trying to burn it with the fuel. The white smoke is steam. There are special gaskets (head gaskets are the primary gaskets) that keep the antifreeze from entering the cylinder area.
* Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe.
* Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Another term for excess fuel is "running rich." Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm.


If you confirm us that is oil smoke, check and keep in mind that the car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

Keep us updated.

Will fuel regulator cause 2001 grand am 2.4 cyclinder run ruff with a slight engine knock at idle. And cause engine to shut off at hight speed.


No it will not, you need to have the knocking sound checked out, it could be rod bearing, or timing chain tensioner, both will damage engine, also need to check fuel pressure and ignition coil packs.

Black smoke coming out of the tailpipe and engine running rough


Black smoke coming out of the tailpipe is a sign that your engine is flooding. Also makes it run rough.

I have a 1997 pontiac bonneville, it's running really rich (white smoke out of the tailpipe lightly) dies when it's at an idle. Changed the coil pack, no change.


If it is running really rich the color of the smoke out of the tailpipe would be dark grey or black. Some white smoke out of the tailpipe is normal in cooler weather until the vehicle engine warms up. Otherwise white smoke may be an indication of the engine burning coolant (cracked head, headgasket etc). I would take it to an auto parts store and have them scan the car's computer for codes. This is usually a free service. A code may be present even if the engine checklight is not on. A trouble code will make it easier to determine what is the cause of your problem. There are numerous things that can cause the problem you are having. Also knowing the mileage of the vehicle will help. Sorry that I am unable to help you more at this time.

1993 lumina euro is blowing black out of tailpipe smells gas


Black smoke is unburned gas. If the car is running fine besides the black smoke, it's most likely the Coolant Temperature Sensor. The part is roughly $20 and an easy fix.

PS- I'm guessing your check engine light is on...
